    BOEMA 2 Group head... on 24/7
    Hi FrenchBean, do you mind if I ask how much it costs you keeping the 2 group beast on 24/7? Im thinking of getting a small 2 group commercial and thought of the potential electricity bills is putting me off a bit. Depends a lot on the active heating duty cycle I guess..

    Just so this is not completely off topic, I currently have:

    Quaha Napoletana (lux grinder built in)
    Stainless/Jarrah tamper from Greg at Coffee Tampers in Adelaide
    4 cup and 8 cup stainless moka pots, never used any more!

    Cheers,

    Dennis

    Re: What Coffee Equipment do you all have?

    lol Dennis...... well um er um............heaps.

    But we use it for more than just coffee, we use it to fill saucepans with Hot water, fill hot water bottles each night, Hot water for many other things as well. We wrapped or boiler which is 11litres with insulation and reduced the working pressure, this doesnt effect the Group head as it is the pump that does that work. I would say the unit works for 2-3 hours out of 24hrs and at .17c per KW I think it costs me about $1.50 a day. But the other option is to put it on a timer, but for us its a luxury that is valuable in many ways.

    Go ahead and buy a commercial unit... the benefits are worth it in the long run.

      Thanks FB, sounds like I wont need to sell the car to support the habit... I know someone with a 2 group faema that might be just the ticket..

        i was given an old bezzera 2 gr, which is on in afternoons and weekends (ecm botticelli 11 is on a timer for mornings)
        its a great option
        only thing is commercial machines are usually not run 24/7 but an hour before day starts
        re working out costs, i thought id count the time the boiler is heated in the cycle- in my case about 1/7th of the cycle and multiply by watts and power cost
        3.9 c kilawatthour x 3 /7 (3000w heater- roughly, on 1/7th time)
        so for my 4 hour afternoon, excluding initial heat up extras, thats about
        6.687c
        of course theres more to it than that, but its not the cost i thought it would be
        brett
        please tell me if im way out and am going to go broke!
        oh and i didnt mention how convenient a 2 gr machine is!

          Wow!

          Youve got cheap power there mate..... our standard tarrif runs at 13.7c per KWH but at even more than three times what you pay, the cost is definitely not prohibitive. Have you factored in the warm-up time from initial power on? This will probably come close to the totals during temperature maintenance .

          Cheers,

            I doubt that....and I think that you will find that most cafes do in fact run their machines 24/7....I, like many other get around 5 minutes before the first customer is with me.....

              point taken about the 24/7 chris-
              perhaps just the small concerns ive talked to - u know u get to a place early in the morning- sorry mate just give us an hour to power the thing up!

              re power cost mal- not sure- just looked on a google search (http://www.uic.com.au/nip37.htm , but this may be what companies buy it from each other for) and no havent factored in the heat up ,although that is surprisingly quick considering large boiler and 2x 1350w elements- about half an hour, turn on the steam to drop pressure twice, either side of a boiler cycle, let pressure build and go (at least run some hot water through handles)
              its good to be ignorant- it gives u somewhere to go- hopefully up!

                Hi Brett,

                If possible, just refer to your last power bill..... should have the various tariffs notorised in there and the one youre looking for will normally be the most expensive tariff listed. Id say from the rate you mentioned above, it could well be the wholesale rate that producers sell to distributors..... would be nice if thats all we had to pay though ,

                Mal.

                  So does anyone else run their machines during the day,say 12 hrs or so at least (if not 24/7)?

                  This wont damage the machine?

                    Commercial machines are designed to run all day. They wouldnt be much good if they werent.

                    I ran my Cimbali M-28 2 group machine 24/7 for a long time. I calculated the cost to be $20-$25USD a month with electricity here running at about 10 cents per KWH. I stopped leaving it on 24/7 when the water supply hose to it sprung a leak in the middle of the night and flooded the house. It is now powered down and the water supply turned off when I go to bed.

                    Running 24/7 isnt expensive, until something goes wrong in the middle of the night. Then it gets very expensive very quickly.

                      re all day all night
                      if im honest i dont leave the bezzera on all the time because im cautious about taking the boiler out and attacking the gasket- pedro at coffee parts said the studs in bezzera boilers can be corroded, although mine appear cadmium plated and ok
                      short form- my machine has a sikaflex patch job and im nursing it along
                      my ecm botticelli ran non stop for a while- now im not to sure thats ideal though- no autofil etc
                      all the best

                        Re: Cost of running a commercial machine 24/7

                        So does the boiler basically just have a thermostat in it that tells the element to come on to prevent it dropping below a certain temperature?

                        Does anyone know how long it usually has to come on for, and how regularly it does this?

                        Cos thats going to basiclaly be the sole driver in the price factor, how long that giant heating element is on for per day.

                            ah okay, thats interesting:

                            22/162 = element on for 13.58% of the time

                            86400 seconds in a day * 13.58% = 11,733.12 seconds heating per day = 3.2592hrs


                            2.7kW * 14c/kWh = 37.8c/hr

                            37.8 * 3.2592 = $1.23/day = $36.90 /month


                            So you can either sponsor a child and have change...or run the coffee machine 24/7. ahah just kidding.

                            Compare this two a one group machine...approx 1300W (think the La Cimbali Jnr is that wattage), and only running it 16hrs a day (8am - midnight)....$11.85 per month.


                            Asssuming the same level of boiler insulation as Telemasters 2grp Bezzera of course, and other element activation.

                              re bezzera boiler insulation - it has none am looking at ceramic durablanket
                              ill let u know what it does- am hoping for about half the cost if what ive read is right
